Inside a Camera          

Shutter Speed

The shutter speed is setting the camera which controls the length of time the shutter is open, allowing the light through the lens to the sensor inside your camera. If you leave the shutter open for too long then too much light will get to the sensor. And when that happens the pictures will come out very pale and white. To get a perfect picture you should leave your shutter open for half a second which allows the right amount of light through the sensor and develop a clear well exposed image. The longer the shutter is open the more chance you will end up with a blurred image.

Depth of field

 Depth of field is the amount of your image before and beyond your focus point that will be in focus. Depth of field can tell you whether or not your subject and background can be sharply focused at the same time. Depth of field gives the perception of being 3D even though it is not.

If things are not in focus it has a shallow depth of field where as in a large depth of field everything is in focus. When you use large depth of field there is no perspective. Narrow or shallow depth of field gives perspective mostly in portraits.

Low depth of field - big number - everything in focus.

Shallow depth of field - small number - just the portrait in focus.
